The disciplinary committee strongly rejected "the many statements made by various arms of public life within this country" over the Contador case.

"They managed to create doubt in the independence and objectivity of this committee," the body said in a statement. "The resolution was the result of independent and deep legal analysis - to reduce the activity of this committee to a mere transcriber of the views of certain media outlets and politicians is simply unacceptable and false."

Contador says he ate meat contaminated with clenbuterol on a rest day during the tour in July. He avoided becoming only the second cyclist to lose his Tour title after Floyd Landis, who was stripped of his 2006 Tour victory after a positive test.

His case highlights a growing concern that clenbuterol can be consumed unwittingly by eating meat from animals who were fed the drug, which helps burn fat and build muscle. It is on WADA's zero-tolerance list.

In a separate case, WADA opted not to appeal to CAS after the German table tennis federation decided not to ban Dimitrij Ovtcharov, who tested positive for a minute trace of clenbuterol from meat eaten in China.

Contador - one of only five cyclists to win the Tour de France, the Giro d'Italia and the Vuelta a Espana - also won Tour de France titles in 2007 and 2009. He was unable to defend his first title in 2008 after his Astana team was banned for doping.
